Answer:
Step-by-step explanation:
The standard equation of direct variation is
y = kx
where k = constant of variation
We start with
y = kx
Since we are give one ordered pair, we use its coordinates for x and y, and we solve for k. We are told that when x = 14 ounces, y = $7.
7 = k * 14
k = 7/14
k = 1/2
Now that we know k = 1/2, we can write the direct variation equation:

Answer:
The Inequality describing the situation is .
Step-by-step explanation:
Let the number of laps he runs be
Let the number of laps he swims be
Now Given:
Time required to run each lap = 3 min
Time required to swim each lap = 2 min
Total minutes he need to exercise more than 45
we need to write the Inequality representing the same.
Solution:
Now we can say that;
Time required to run each lap multiplied by the number of laps he runs plus Time required to swim each lap multiplied by the number of laps he swims should be greater than Total minutes he need to exercise.
framing in equation form we get;
Hence The Inequality describing the situation is .
Question #1
Part A:
The y-intercept can be found when x = 0. If you look at your table, when x = 0, y = 5. So the y-intercept is 5.
Part B:
The slope is 22.
Part C:
y = mx + b
y = 22x + 5
We are given 225 as the range, or in place of y.
225 = 22x + 5
220 = 22x
x = 10
The domain is 10.
Question #2
Part A:
(2,255)
(5,480)
Standard form is Ax + By = C
Let's plug this into this form first:
Now, let's make it into Standard Form.
What, which is in the box, is your final answer. :)
Part B:
Function notation simply means replacing y with f(x).
We had y = 85x + 55
So your answer is:
Part C:
Using the final answer which we got in Part A, we would know that the y-intercept is (0,55) and the x-intercept is (-55/85, 0). We would plot these 2 points, and then draw a line between them. :)
